An apparatus an unmanned aerial vehicle recovery system is provided. The apparatus includes a base to mount to an unmanned aerial vehicle. The apparatus further includes a housing to engage the base. In addition, the apparatus includes a parachute disposed within the housing. Also, the apparatus includes a deployment mechanism to deploy the parachute. The deployment mechanism is to eject the housing away from the base upon a triggering event.

A glide module mounted to an unmanned aircraft system and an unmanned aircraft system having the glide module are proposed. The glide module includes a container including a storage space therein; an air resistance member stored in the container; an ejection member performing ejection of the air resistance member; a glide member performing glide of the air resistance member; and a glide control member controlling the ejection member and the glide member, wherein the glide control member performs an autonomous flight under a previously input condition by controlling the glide of the air resistance member. An unmanned aircraft system including the glide module is also disclosed herein.

A parafoil for operation at high altitudes, in low density air, or at low airspeeds, and methods for opening same. Some versions of the parafoil comprise flexible members connected to the parafoil canopy. When the parafoil canopy is in a stowed configuration, the members are deformed, storing elastic energy. When the canopy is released from its stowed configuration, the members spring back to their undeformed shapes, thereby opening or assisting with opening the canopy. The flexible member may also be attached to a base structure, which is attached to the payload. The members may comprise rods or hollow tubes that can be flexed using a fulcrum near the base structure, or a spacer plate, so that the ends connected to the canopy are restrained by a parachute bag containing the stowed or packed canopy. The parachute bag can be opened prior to or during detachment of the parafoil from the flight vehicle

The present disclosure relates to a drone including a drone body; a drone body battery provided in the drone body and responsible for supplying power to the drone body; a parachute kit detachably coupled to the drone body and including a parachute therein; a battery detector provided in the parachute kit and responsible for checking the state of the drone body battery; and a parachute controller for controlling the parachute kit depending on the state of the drone body battery detected by the battery detector, and to a parachute kit for drones. According to the present disclosure, the drone is configured so that, when the power of the parachute kit capable of being attached to or detached from the drone and the power of the drone body are cut off, the parachute is unfolded by spring elasticity or compressed air. Therefore, breakage of the drone may be prevented, and damage caused by drone crashes may be minimized.

Disclosed is a technique for landing a drone using a parachute. The technique includes a parachute deployment system (PDS) that can deploy a parachute installed in a drone and land the drone safely. The parachute may be deployed automatically, e.g., in response to a variety of failures such as a free fall, or manually from a base unit operated by a remote user. For example, the PDS can determine the failure of the drone based on data obtained from an accelerometer, a gyroscope, a magnetometer and a barometer of the drone and automatically deploy the parachute if any failure is determined. In another example, the remote user can kill the drone, that is, cut off the power supply to the drone and deploy the parachute by activating an onboard kill switch from the base unit.

This invention relates to the use of an automatic safety parachute deployment system for drones (UAVs), which utilizes an airflow trigger that deploys one or more parachutes under certain aerodynamic conditions from the upward airflow during a flight malfunction. The system is mechanically activated without the use of electronics, batteries or an ejection spring which reduces the complexity and weight.
